Generating XML in PHP
Example
<?php
// XMLWriter for large XML
$writer = new XMLWriter();
$writer->openMemory();
$writer->setIndent(true);
$writer->startDocument("1.0", "UTF-8");
$writer->startElement("users");
foreach ($users as $user) {
$writer->startElement("user");
$writer->writeAttribute("id", $user["id"]);
$writer->writeElement("name", $user["name"]);
$writer->writeElement("email", $user["email"]);
$writer->endElement();
}
$writer->endElement();
$writer->endDocument();
$xml = $writer->outputMemory(); Pro Tip
Use XMLWriter for generating large XML files — it streams output without building the entire DOM tree in memory.
